Auto-Refresh Preview Reloads: CodePen Editor Lacks a Configurable Debounce or Cancellation Boundary

CodePen's Auto-Refresh feature reloads the preview pane whenever the editor detects a change in HTML, CSS, or JavaScript. The current public release triggers this reload on every keystroke, producing rapid consecutive updates that can cause preview flicker and strain when scripts are computationally heavy.

There is no documented editor setting or API to debounce, throttle, or delay these reloads, nor is there a mechanism to cancel an in-progress preview refresh. Long-running JavaScript can leave the preview unresponsive, and the absence of a configurable timeout means developers cannot bound how long a reload attempt persists. Because this behavior reflects the latest public state and may shift with future updates, practical verification against the current editor version is required to confirm whether any hidden preference exists.

Is there an undocumented preference or URL parameter that introduces a debounce interval for Auto-Refresh? Does CodePen expose any programmatic hook to abort a pending preview reload or enforce a maximum reload duration? If not, is the lack of debounce and cancellation controls an intentional design constraint or an unresolved gap in the editor's configuration surface?
